So, you don’t want plastic guns made on a 3-D printer? You want a metal gun. You don’t care about metal detectors at an airport. You are concerned about gun registration.
It looks as though your answer is almost here. Possibly by the end of summer, you will be able to buy a computer-driven desktop metal fabricator. So will a lot of people.
Within five years, this technology will be everywhere. It will let people build all sorts of metal equipment. Maybe this product will not pan out, but something comparable will.
This is the wave of the future. We are going back to what we had in 1790: cottage industries. Only the cottages will be factories.
This is decentralization on a scale we can barely imagine.
Sales taxes? Gone. Tariffs? Gone. Registration? Gone. Buy a blueprint, download it, and DIY.
Next stage: encryption. Let the NSA follow the digits. So what?
The more fabrication machines there are out there, the greater the noise — data overload. Noise is our friend.
